2000 Subaru Forester Fuel System Problems

Your fuel filler pipe and its mounting hardware have rusted through, creating a risk of fuel leaking when you fill up your gas tank. Your check engine light is on with error code 0440, which relates to this fuel system issue. The rusted components will need to be replaced to safely operate your vehicle.

Your check engine light came on due to a vacuum or pressure problem in the fuel system. Replacing the gas cap didn't fix it, and further inspection found that the gas filler pipe had rusted completely through, while the fuel lines developed severe corrosion that caused the rubber tubing to separate from the filler pipe. Sand and salt had accumulated under a plastic cover over the rusted area. The repair will likely require replacing the corroded gas filler pipe and fuel lines with new components.
